Welcome to 3rd Grade!
    Mrs. Tanya O'Brien 
    My name is Mrs. O'Brien and I teach third grade at Thornton Central School. I began my love of learning at Thornton Central School many years ago as a student. After attending college, I came back to TCS and worked as a paraprofessional and realized just how much I loved working with children and decided to further my education and become a teacher. I then taught for many years outside of the Thornton area. I am so happy to be back at TCS! This will be my third year teaching at TCS and I am looking forward to another amazing year! 
    Outside of school I enjoy spending time with my busy family hiking, traveling and exploring our amazing world. I look forward to meeting and getting to know all of you!
